To provide a taxi pickup service system for quickly and surely picking up a passenger who requests taxi pickup.

When the taxi driver understands this, the control center side system 1 notifies, by e-mail, the portable telephone terminal 2 of the passenger of the acceptance number, and transmits the acceptance number, the location information of the passenger and the image of the passenger to the on-vehicle system 31 of the taxi 3. The on-vehicle system 31 displays the location of the passenger on the map of a monitor screen, and displays the acceptance number and the image of the passenger on a monitor screen when arriving at the pickup location.
